Please refer to FIG. 3E and FIG. 3F, in which thewaterproof elastomer 32 is substantially a hollow cylinder structuremade of elastic materials with fluids (liquids or gases), being filledtherein. The waterproof elastomer 32 includes an elastomer body 321, anda channel 322 is opened at a center thereof. The channel 322 has aplurality of protruding portions 323 defined annularly around an innerwall thereof and radially protruded inward along the cross-sectionalplane of the middle segment of the waterproof elastomer 32 to blockmoist from moving from one end of the channel 322 toward the other endof the channel 322, such that the waterproof elastomer 32 is watertight.Please refer to FIG. 3F again, in which when the first electrodeterminal 221 of the battery 20 a is connected electrically to the secondelectrode terminal 231 of the battery 20 b, the first electrode terminal221 is passing through the elastomer body 32 via the channel 322 andconnected electrically to the second electrode terminal 231; at the sametime, the protruding portions 323 of the elastomer body 321 is pressedoutwardly toward a direction perpendicular to the inserting direction ofthe first electrode terminal 221 by the first electrode terminal 221, sothat the elastomer body 321 is closely attached with the receiving spaceof the second electrode terminal 231 and the moist cannot enter into thereceiving space from the gap between the elastomer body 321 and thereceiving space. Additionally, as shown in FIG. 3F, due to the pressurecaused by the first electrode terminal 221 and the circumstances, themiddle part of one end of the elastomer body 321 which is exposedoutside (that is, one end far from the battery core 201), is recessedinward, and the outer periphery thereof is not compressed because of theincreasing of the pressure inside the elastomer body 321. Furthermore,as shown in FIG. 3E and FIG. 3F, the second electrode terminal 231 has aterminal inserting portion 2311 and an abutting wall 2312.
